The record

Purpose: projectM is an open-source music visualizer that turns audio input into real-time visuals.
Library: The project provides libprojectM, a reusable shared or static library for application development.
MilkDrop compatibility: The library reimplements Winamp MilkDrop and supports user-contributed visualizations.
Audio analysis: libprojectM analyzes PCM audio using beat detection and FFT, then renders visualizations with OpenGL.
Presets: Preset files define visualizations using pixel shaders and MilkDrop-style equations and parameters; the library itself does not ship with presets.
Desktop frontend: The projectMSDL frontend listens to audio input and produces visuals, with standalone options listed for Windows, macOS, and Linux.
Development status: The repository says available end-user frontends are development previews that may be incomplete and contain bugs.
Mobile availability: The repository links to an Android app on Google Play and says the Play Store apps are not created or supported by the projectM developers.
Integrations: The repository lists GStreamer and Qt-based desktop apps, and names Kodi, Silverjuke, and VLC as third-party integrations.
Integration support: The projectM team says third-party integrations are not developed or supported by its development team.
Security and license: The core projectM library is released under the GNU Lesser General Public License 2.1.
Support: The project directs users to GitHub issue trackers for library, standalone app, Windows Store app, and Apple Music plug-in issues, and to Discord for contact.
Audience: The repository describes libprojectM as a library intended for use in application development, with source and developer documentation available.
History: The official site says projectM was initiated in 2003 and released in 2004 to bring MilkDrop-style visualizations to non-Windows systems and open-source environments.
